This .invention refers 13o-improvements in devices for singeing threads of'any kind kand particularly ,toV an. insertion piece f or, gas. singeing chambers, of the type, which are provided with a tubular member through which the thread to be singed passes'in-the longitudinal direction and. which together wiftlian outer wall deinesa gas distributing chamber from which the combustible gas flows linto Ithe interior of the tubular membei'. f

According to the 4present inventiony the wall .of :the tubular member is weakened, i. fe.kept thinner on a portion of the circumference 'of the said member whereby the recess on the circumference of the vmember which causes .the weakening of -the wall forms a ygas .distributing chamber and the weakened wall forms Aa glowing surface.

'g burner tube of this type may be inserted into type for better utilizing' the heating powerv Y I existing :singeing vapparatus of the known of the gas. i

Preferably the tubular member is provided in Jits'weakened part with longitudinal slots arranged .diametrically opposite yeach other through which the combustible gas passes lso vthat two flames 'pointing towards each other 'Y Yand ooinpietely surrounding. the thread to be aube, Y v f A VlFig.- 7 `shows in `a longitudinal section the Ysingeing oha-mber, the additional tube,

The latter is the case it the enlarged parts of the slots 9 only permit a passage of the gas whilst the part of the slots 9 between the enlarged parts 10 does not register with the slots 5 of the tubular member 1. `In this mannerthe slots 5 of the tubular member 1 are closed to some extent and the gas passes member 1 only as far as the enlarged parts extend so that a correspondingly weaker flame is produced as is necessary when treating certainl yarns or threads.

The tubular'meinber 1 may also be inserted in other bodies forming singeing chambers instead of ina singeing tube A..l

rIn the general arrangement illustrated in Figs. 10 and 11 a plurality of singeing tubes one beside the other on a frame 11i and the threads B are unwound from bobbins 15, they pass through eyelets 16 andthrough the singeing tubes A in which they are subjectedto the action of the gas flames. rlhe combustible gas is supplied by the conduit i and the combustion residues are removed by the action ot' the suction fan 17 for which purpose the upper ends ot the singeing tubes A are connected by the 'branches 18 and the conduit 19. The siiiged thread passes over guides QOvto a winding device 21 and is wound on reels 2Q.
